The TS-MPPT-600V-TR modes are controlled by a manual transfer switch. After installation has
been completed, there are few operator tasks to perform. However, the operator should be
familiar with the operation and care of the TS-MPPT-600V-TR as described in this section.
4.1 Using the Transfer Switch
The transfer switch allows the user to switch the PV array between the grid-tie inverter and the
TriStar MPPT charge controller. The two positions are illustrated in Figure 4.1 below. Grid-tie
operation is engaged in the horizontal positions; battery charging is enabled in the vertical pos-
tions. In the event of a power outage, move the transfer switch position from “Grid Sell” to “Bat-
tery Backup”. This will redirect the solar array energy from the Grid-tie Inverter to the charge
controller, allowing the backup battery to receive charging current during the outage. When the
AC grid is restored, move the transfer switch back to “Grid Sell” position to resume sell-back of
your solar array energy.
